• Eli Lilly's Zepbound (tirzepatide) led to a 20.2% average weight loss, significantly outperforming Wegovy (semaglutide) at 13.7% in a 72-week clinical trial.
• The SURMOUNT-5 trial included overweight or obese adults without diabetes, showing Zepbound users experienced 47% more relative weight loss than Wegovy users.
• Zepbound, a dual GIP and GLP-1 receptor agonist, helped 31.6% of participants achieve at least 25% body weight loss, compared to 16.1% with Wegovy.
• The study's findings may influence treatment choices, with Zepbound potentially becoming a preferred option for greater weight loss outcomes, pending further data on tolerability.
